DNA-Model with 12 base pairs

Illustrative molecular models made of plastic with which the DNA double helix can be established: The bases are represented by flat plastic body in four different colors. About the shaping of the model, it is only possible to sew together the complementary bases (adenine and thymine, guanine and cytosine). The pentose phosphate backbone is also assembled from deoxyribose and phosphate elements. The models can be built as a double helix using the supplied stand or be laid flat to show, for example, the process of replication.  Includes: 6 blocks of the bases: adenine, uracil, guanine, cytosine 24 ribose- and 24 phosphate blocks 12 spacer colorless 1 instruction manual (in English) 1 tripod base plate and bar with an end cap Dimensions assembled (mm): 240 x 110 Delivery in solid plastic box
